An odd spin...

The recent exchange about vaccines, et al, reminded me of the findings
regarding Lyme disease. It was reported that ticks taking a meal from
humans having received the Lyme innoculation became immune to the
disease. Hmmmm. Might it be possible to develop a vaccine (for
something) and introduce it into a vector (mosquitoes or other blood
feeders) for its subsequent distribution into the human population?
